FREEDM 84A1024L ASSP Telecom Standard Product Data Sheet
Multiplexed Address Data Bus. The multiplexed address
data bi-directional bus AD[31:0] is used to connect the
FREEDM 84A1024L to the microprocessor.
During the address phase when ADSB = 0, AD[1:0] are
ignored as all transfers are 32 bits wide.
AD[31:0] is sampled/updated/tristated on the rising edge
of BCLK.
long-word address is present on the address/data bus
AD[31:2].
ADSB is sampled on the rising edge of BCLK.
low during the address cycle (as defined by ADSB)
FREEDM 84A1024L register accesses.
CSB is sampled on the rising edge of BCLK.
Write/Read. The write/read (WR) signal is evaluated
when the ADSB and CSB are sampled active by
FREEDM 84A1024L. The BUSPOL input pin controls the
polarity of this input.
WR is sampled on the rising edge of BCLK.
Burst Bar. This signal is evaluated when the ADSB and
CSB are sample active by FREEDM 84A1024L. When
low, this signal indicates that the current access is a burst
access (and the BLAST input can be used to detect the
end of the transaction).
BURSTB is sampled on the rising edge of BCLK.
Function
Address Status. This signal is active-low and indicates a
Active Low Chip Select. The chip select (CSB) signal is
